Abstract
In an array of data storage disks, a data validation system for data arranged in corresponding sectors of a sector group that includes a parity sector. Each user data sector in a sector group is assigned at least two of a plurality of validation fields for placement of a validation stamp. No two data sectors are assigned to identically corresponding sets of validation fields. In the parity sector, there is a parity entry in each of the validation fields created by combining all of the validation stamps in the corresponding validation field throughout the sector group. The validation fields are used to detect partially completed writes into the array of data storage disks.
